Reprogramming the "brains" of the car's on-board computer. What is flashing

The little boy, carrying a baseball bat and a ball, ran into the backyard to play. Running out of the house, he muttered under his breath: "I'm the best receiver in the world." Then he threw the ball into the air, swung it with all his strength and ... past. Without a moment's hesitation, he picked up the ball, tossed it into the air again, saying, "I'm the best receiver in the world," swung the bat again with all his might. Swing - and miss. And try again. He tossed the ball into the air again, with focus and determination, and saying, "I'm the best receiver in the world!" tried to hit the ball. He swung with all his might. And fail again! The little boy put down his bat and smiled broadly. “Do you know what? he said. "I'm the best pitcher in the world!"

This is exactly what is called the right attitude! Sometimes you just need to make the decision to see the bright side of a situation. When something doesn't turn out the way you wanted, instead of moaning and complaining about fate, try to see something good in the circumstances. Fill your mind with kind, good thoughts.

The brain is like a computer. What program you install in it, so it will work. And how stupid it is to sit and complain: “I hate this computer! He never does what I need and never gives the right answers!” Think about it: you can buy the most powerful processor in the world, but if you install pirated software on it or the installation fails, it will never work the way its manufacturer intended.

In addition, today there are myriad computer viruses lurking in cyberspace, just waiting to destroy your HDD and all the information you store on your computer. Such viruses can penetrate any, even the most advanced computer and infect software. It doesn't take long for your computer to freeze or intermittently. And you can't open desired program or an important document. So often we unwittingly send this virus to our friend, family member or business colleague, exacerbating the problem by infecting their system with the same virus that infected ours. Usually these kinds of problems arise not because our computer is faulty, but because someone has reprogrammed the software or infected quality, expensive programs.

In the same way, we very often allow negative thoughts, words, or other cunning viruses to enter our minds, subtly altering our software or distorting the information and things we hold so dear. We were created in the image of God. Even before we were created, He programmed us to prosper, be happy, healthy, and whole. But when our thinking becomes corrupted, infected, it is no longer in harmony with the Word of God. We begin to make serious mistakes and make bad decisions. We go through life with low self-esteem, filled with anxiety, fear, constantly feeling inadequate, incapable of anything and unprotected. The situation is worsened by the fact that we transmit such a negative attitude to others.

When you suddenly realize that something similar is happening to you, you need to reprogram the computer as quickly as possible. You must change your thinking. Understand you in order.

God created you and programmed you to win. But until you align your thinking with the user manual, with God's Word, you will never be able to function at your full potential.

God created you and programmed you to win.

Problem in thinking

Some time ago I had a conversation with a man who said, "Joel, I've watched your sermons on TV about how to be happy and enjoy life, but you know, I don't think it works for me." He explained that five or six years ago he had to deal with a very painful breakup in a relationship. He was literally heartbroken and devastated. He said, “I feel like I just can't deal with these emotions. Every morning I wake up depressed. I live day by day and I can't shake off this sadness. I return home, go to bed, and again depression overcomes me. He informed me that he had already met with several consultants, but still did not see the slightest progress. "Do you think you can help me solve my emotional problems?"

I answered him quite frankly: "Sir, to be honest, I don't think you have an emotional problem at all."

"What do you have in mind?"

“What do you think about the very first moment you wake up in the morning?”

“I think about how alone I am and how much I have been hurt,” he replied.

“What do you think about during the day?”

"I think about how messed up my life is, how many mistakes I've made and how much I want to start over."

"What do you think about when you go to bed?"

"All about the same."

“Sir, I am not a psychologist or a psychiatrist, but it seems to me that everything is in order with your emotions. They work exactly as God intended them to. Our emotions simply react to what we think. In and of themselves, they are neither positive nor negative. They just let us feel what we think. If you go around in circles constantly thinking about something sad, you will feel sad. If you think of something evil, you will get angry. But if you go through life cultivating thoughts of happiness and victory, you will be happy. You will be the winner. You can't spend the day thinking about all the people who have hurt you and all the mistakes you've made and still somehow hope that you can live a happy, positive life. You need to let go of the past and start contemplating that God has an amazing future in store for you. He prepared a new beginning. Begin to meditate on the fact that God promised to turn this situation around for good. Make a decision to think positive. You have to reprogram the mental computer, and when you do that, your emotions will return to normal."

The Bible says, “I have set before you life and death, blessing and cursing. Choose life” (Deut. 30:19). And it's not something that will happen once and for all. It is a decision that we have to make day by day, sometimes several times a day. We must decide to focus on something good. Evil will always be around us. We must decide to focus on what is right instead of thinking about what is wrong. Make the decision to focus on what you have, not what you don't already have. Make a decision to think right.

Negative thoughts are sure to knock on your door, but you can let them in or not. If you choose to keep a close eye on that door and focus on God, the Bible says that God will keep us in perfect peace (see Isaiah 26:3). You can keep the peace in the midst of storms if you just learn to choose the right thoughts. This means that at the moment when difficult times come in your life, instead of focusing on your problems, you must decide to focus on your God. Focus on the fact that Almighty God is on your side. Focus on the fact that He promised to fight for you. Focus on the fact that no weapon designed against you will succeed. If you start cultivating these kinds of thoughts, you will be filled with faith and confidence, no matter what happens around you.

Perhaps you have experienced a severe disappointment, and perhaps everything in your life did not turn out the way you would like. Maybe people treated you wrong. Maybe you have experienced the pressure of failure. But with God you will never reach a dead end. He always has a new beginning for you. Start thinking about a solution. Reflect on the fact that God still has an amazing plan for your life. When one door closes, God always opens another, bigger and better. But you have to do your part - to stand on a position of faith and not lose hope.

Understand, this is not a one day war. We can never get to a place where we don't have to face negative, destructive thoughts. Therefore, the sooner we learn to guard our minds and control our thoughts, the better.

No matter how many years we live in trust in the Lord or how positively we live, we will all be affected by disappointment from time to time. This is part of the price we pay for living in our sinful world. And no matter how hard I try to maintain my positive attitude, I am still not immune from such attacks.

keep calm

In December 2001, when Lakewood Church decided to lease the Compak Center in Houston, we signed a sixty-year lease that allowed us to occupy a huge sixteen thousand-seat basketball court. Our church was in a state of joyful excitement, and we could not wait to finally begin the reconstruction.

But another company, which was also interested in the space, filed a lawsuit to prevent us from moving. Naturally, we were upset by the delay, but after praying, we received confirmation that God wants us to continue moving in the intended direction. In March 2002, we made a decision and made a conscious commitment, declaring that we want to go all the way.

Unfortunately, in the fall of that year, the lawsuit flared up with even greater force. Throughout the winter, the disputes did not stop. As a result, we were sent a notice that we were being summoned to court in the spring of 2003. Our lawyers have already warned us: there is not the slightest chance that our opponents will give in to us without a fight. Too much was at stake. We discussed our possibilities, assuming various developments, spoke with lawyers who clearly demonstrated our chances of winning or losing, told us how much money we would have to spend and how long it would take. As I looked through all those dreary reports, the situation seemed almost hopeless to me. Even if we did win the lawsuit, it could still be stuck in the courts for years, given the endless appeals that would be filed. And all the while, huge sums of our money will be at risk.

During this endless period, I often woke up in the middle of the night with my mind under endless attack of thoughts that haunted me: “You made a terrible mistake. You told all these people you were going to buy Compak Center. You told them your plans. You took their money. Think about what's in store for you if you lose this suit? You're just making a fool of yourself. what do you think will happen if this whole situation is stuck in our judicial system for like eight or nine years?

Thoughts of failure and inevitable loss bombarded my mind: "It's impossible. It just never works. You'd better just take your money and move on." I was tempted to try to fix things on the basis of his own reasoning. I was tempted to lose my joy. But at the same time, I had to make a decision about whether I would focus on the lies of the enemy, whether I would become depressed, and whether I would interfere with God's work or still continue to trust Him and believe that He is fighting on our side. . Will I choose to focus on the fact that God is in control and that He directs our paths?

I made the decision to move with God. When all these thoughts of disbelief and doubt came crashing down on me, I did everything I could to resist them, to reject them. I made a conscious decision to focus not on problems but on God.

When the thought came up: "It's impossible", I rejected it and reminded himself that with God all things are possible. When the thought came up: "It was the wrong decision, you will never succeed", I He rejected it and reminded himself that everything works together for good to those who love God. When the thought arose the opposing company is too strong and impossible to win, I rejected it and said that no person or company could stand against the Lord. If God is for us, who will dare to rise up against us? When I was tormented by thoughts: “It will lead to nothing but trouble and confusion. You will drag your church through all this dirt, and everything will end in disappointment, I learned to raise my hands and proclaim, "Father, You said that when we walk in purity, You will keep our feet from stumbling, so Father, I thank You that You keep us from error."

Whenever these negative, disappointing thoughts entered my mind, I used it as an opportunity to thank God for the victory to come. I knew that if we plunged into doubt and unbelief, God would not be able to work to resolve our situation. And I didn't want any of what I was doing to stop God from giving us the victory.

The appearance of an on-board computer in domestic cars pleasantly pleased many motorists and patriots of domestic cars. Now, indeed, many do the so-called CHIP tuning, not at all considering the firmware to be child's play. Indeed, there are several useful features here. After all, if you think quite a bit, it becomes obvious that reflashing the on-board computer program will cost many times cheaper than changing parts of the exhaust system as a result.

Flashing is much easier and, if desired, it is easy to do it yourself. Gas installations such as Euro-3 and Euro-4 are initially tuned to the processing of high-quality foreign fuel. Only by resorting to flashing the on-board computer can you avoid numerous visits to the service station in the future.

What is flashing

Flashing a car's on-board computer can be both effective and malicious. It all depends on the purpose of this action.

Simply put, flashing the on-board computer is a change in the set parameters that control all the processes of the engine. By slightly changing the settings of these programs, you adjust the operation of the motor and the whole car as you wish.

The ability to reflash your cars arose immediately after the appearance on the automotive electronics market of such equipment as an electronic on-board computer. This small device replaces the functions of the control lamp unit with a convenient remote control with an online display of all the options for your car.

How to make smart changes

If the goal is to achieve the most convenient operation of the car, when, based on the owner’s own experience, he wants to increase or decrease the driving parameters proposed for change, then flashing the on-board computer is a good and economical idea.
Perhaps the owner of the car is determined to use all the available reserves of engine power in order to participate in racing competitions or even just for everyday driving, then this idea should be carefully considered.

In each of these situations, the motorist himself decides how to tune his car with the real mode of its operation. But the reasons for flashing the on-board computer of your car may be such as these:

the car has noticeably lost the dynamic properties of the ride;
the engine stalls in the most unpredictable situations;
the car starts late;
fading start in the cold season;
poor response of the car when you press the gas pedal;
stable idle operation is disturbed.

All the reasons from this list are easily eliminated after flashing the BC.

A warning! When choosing the most economical mode of fuel supply, you risk contaminating the exhaust and fuel system with soot. As your riding style becomes more measured, the operating pressure will not be sufficient to fully purge the entire system.

In simple terms, many motorists do not quite imagine what to actually expect from flashing the on-board computer. They expect to get significant savings by reducing fuel consumption or expect their car to become super-fast beyond recognition. The on-board computer is arranged a little differently. Therefore, software changes must be made taking into account the normal operation of the car.

But still, many cars can really be revived a bit with the help of firmware and make it drive faster. It's really little effect on fuel consumption.. This happens because their factory firmware complies with strict environmental international standards and is maximally squeezed within this framework.

Flashing should be treated easier

Motorists often treat their car with soul. Once upon a time, people treated horses this way, but now the world has changed, and people along with it. We have seen a lot in the past few decades, and there is still more to come. A person who thinks stereotypically is a frequent phenomenon, or rather, each of us is sometimes ready to vote for the proven old than to support the unknown new.

Flashing the on-board computer should be treated in the same way as reinstalling Windows on a computer. As soon as the first computer appeared in the car, everything changed dramatically. By choosing good program and by doing the whole procedure correctly, you will notice how your car will behave differently. More lively!

In other words, you need to correctly understand the capabilities of your car in order to make such changes to the central control unit. To do this, you will need a Windows-based personal computer. It doesn't matter if it's a laptop or a home desktop computer, and read the appropriate guide on how to flash a car's on-board computer.

How to reflash the Matrix on-board computer

Work algorithm:

Before you start learning how to flash the on-board computer of a car, be sure to check your engine type. Since on-board computers are different types and markings, and the configuration machine, you must select the correct program for flashing. When the car is equipped with a gas installation, flashing the on-board computer removes many errors owing to what, fuel consumption and quality of the course is normalized.

To date, the demand for the flashing service has arisen very quickly and a large variety of programs have followed. Some of them work perfectly, others do not work as we need, which often causes breakage and new costs. Therefore, you need to be sure that the program you choose was created by guys with even hands.

Here is a small list of programs you can trust:

How will the car drive after the firmware

Definitely, this question is asked by every car owner who decides to experiment with flashing the on-board computer. Will the car actually drive more dynamically? Considering that experts in this matter never give recommendations to increase power to full, it is worth paying attention to this. This mode can disrupt both ride comfort and reduce the maneuverability of the car.

With a slight increase in power, you should achieve maximum throttle sensitivity. Thus, the flow may not change, but you no longer have to deeply sink the pedal. Responding to a light touch on the gas pedal, the car does not load the engine, but is actively gaining momentum.

After a successful flashing of the BC, you can feel it in the following changes:

you will notice a more elastic operation of the motor;
management will become much more comfortable;
acceleration will be noticeably more dynamic;
more stable and smooth traction;
on average, both power and torque increase by 15%;
the indicator of the highest speed will become higher;
the mechanics when shifting gears behaves more smoothly, the automatic machine thinks faster;
driving style will better adjust fuel consumption.

In any case, if you understand that each malfunction has possible reason, and, consequently, a way to eliminate it, you will certainly be able to do everything yourself. If, of course, the instruction is attached in Russian, it is worth reading.

Currently, more and more vehicles are being produced equipped with. So far, not everyone can afford such cars, but in the near future the number of cars without "brains" on our roads will decrease at least twice. Despite the growing popularity of on-board computers, very often their work leaves a lot to be desired. Therefore, as “brainy” cars increase on the roads, the service associated with their maintenance is becoming more and more popular - car computer firmware.

The main goal pursued by the creators of on-board car computers is to provide maximum comfort to the driver and passengers during the trip. In the case when such a device does not cope with its work, it needs the so-called (from English microcircuit adjustment).

Flashing the brains of a car is the most optimal and least expensive way to increase, improve the dynamics of a car and at the same time not remake the engine.

For those who are not yet very good at information, we explain that the electronic brains of a car are an electronic engine control unit, the operation of which is determined by some program. By changing its parameters, you change the behavior of your "iron friend".

The manufacturer's firmware is characterized by the presence of a certain reserve for the ability to increase power, torque, speed and maximum engine speed by changing the software in the "brains" of the car. The fact is that cars, the "brains" of which are strongly clamped into the framework of the norms in terms of the level of toxicity. Chip tuning was invented precisely in order to expand these limits.

Reasons for flashing

The factory firmware of domestic and foreign cars is far from perfect. This is especially true for domestic manufacturers, who can produce a car with a frankly defective one. Criteria for determining marriage are easy to track:

the car has sluggish dynamics;
the engine can stop at the most unexpected moment in any mode;
failures are present;
uncertain start in the cold season.

Such problems can only be eliminated by changing the engine software. It is worth noting that you do not need to be stingy and it is better to reflash the brains of the car than to buy a new catalyst, oxygen sensor, particulate filter, etc., when they fail due to improper engine operation.

Also note that Euro-3 and Euro-4 systems are designed to use expensive and high quality. Firmware is also required for safe filling of domestic gasoline.

Which programs are better to choose

At present, a market has already formed for adjusting firmware even in the vastness of our country. A program for flashing a car must necessarily meet all the quality standards of such information products, otherwise, instead of getting rid of problems, you will double their number.

The most famous and reliable foreign manufacturers of programs for the on-board car computer are chiptuning.com, chip-tuning.de, upsolute.com. Among domestic software producers, SMS Software, chipsoft.ru, adact.ru, chiptuner.ru and pauluschip.ru have proven themselves well.

Similar ready-made programs can be used if you own a stock engine.

Stock engine firmware

You can reflash the on-board computer at a car service. In the first case, you will have to pay a considerable amount of money, and in the second, you will spend a small amount of time and deal with the manual for this operation.

On the video - the firmware of the Chevrolet Aveo on-board computer:

Brief instruction that the new software on the car:

Before starting the flashing, you should write down the version of the hardware implementation of the car computer. You will find it in the top line when power is applied.
Now you need to download the update file and bootloader that match the version of your on-board computer. If it doesn't match, it won't work.
The next step is to connect the adapter's COM port to personal computer and connecting it to the on-board computer using a connector. It is also necessary to connect power to a special connector, but do not supply it.
Now run the Boot24 program. A window with several sections will pop up on the screen: “Open firmware file”, “Select COM port”, “Download”.
First, select a COM port. A small triangle will appear on the screen, clicking on which will open a list of available ports. Now select the port to which the K-line adapter is connected, and click the "OK" button.
Next, click the "Open Firmware File" button. In the window that appears on the screen, specify the file with the firmware (*.rom) and click the "OK" button. This file is located in the folder with the program itself.
Now you should turn on the power of the on-board computer and click the "Download" button. On the display you will see the inscription "Turn on the BC". To cancel the installation, click Cancel.
After turning on the power, the utility will start loading, which will be indicated by the growth of the progress indicator of the installation process. If you messed up somewhere, the download process will not start. Upon successful installation, the message "Download completed" will pop up. After that, your on-board computer is ready to serve faithfully again.

What to expect from flashing

Most motorists are concerned about only one question regarding chip tuning - how will it change qualitatively? Experts advise not to chase power, as the maximum increase in horsepower can adversely affect the comfort in driving a car. Smooth movements of the car can be replaced by jerks and twitches in different driving modes.

On the video - firmware BC Lada Grants:

Choose a program that will add not speed, but comfort in driving and save you from factory defects.

Correct tuning of the brains of the car will lead to the following changes:

engine operation will become more elastic;
traction will be more even and smooth;
the comfort of driving the machine will increase;
power and torque will increase up to 15%;
will improve;
the maximum speed indicator will increase;
jerks will disappear when shifting gears and the thoughtfulness of the automatic gearbox;
slightly reduced fuel consumption.

In addition, during flashing, you can turn off lambda probes, catalysts, adsorbers, etc. Flashing the brains of a car helps to increase the resource of the power unit, as engine operation is optimized, factory errors and excessive depletion of the fuel-air mixture in high power modes are eliminated. Euro-3 and Euro-4 systems. Fuel consumption may remain the same. However, during acceleration, it will no longer be necessary to stomp the gas pedal, which will significantly reduce the load on the engine.

If you have spent a considerable amount of money and purchased a smart car, then do not be stingy and reflash its “brains”. The result will not be long in coming and will fully pay off!

The article was published on the site Boris Lion June 21, 2008 - http://borislion.ru/ (The initiative for writing this article belongs to Boris Lion, for which many thanks to him)

From this article, you will learn about automating routine actions on your computer. And also I will talk about how and with what help this automation can be organized.

Quite often on the computer you have to do some simple, but repetitive actions such as mouse movements, keystrokes, text input.

This is monotonous and completely uninteresting work. How I wish she could do it herself! Or that the computer would take over its execution.

That's quite possible.

To solve this problem, there are special programs that allow you to record user actions (mouse movements, keystrokes) and then play them back at the right time.

Roughly speaking, you show the computer what it needs to do, and then it will reproduce your actions when and as many times as you need.

At the same time, the software with which you work will consider that the reproduced actions come from the user, from you.

Thus, you can automate any repetitive actions on your computer.

I tried several automation programs and most of all I was satisfied with the development of Denis Safonov called AutoClickExtreme:.

The AutoClickExtreme program serves just to automate repeated user actions.

With it, you can process tables in Excel, work through a large number of files, make a backup copy of important data, and also transfer databases from one format to another.

This is only a small part of the possible applications of this program. With it, you can automate almost any simple repetitive task.

Here are the useful features of AutoClickExtreme.

The ability to quickly play recorded actions. A computer is faster than you and can do the same things dozens of times faster.
Ability to manually edit the result of recording actions. For example, you can remove unnecessary actions in the recording, such as unnecessary mouse movement.
Ability to insert text of any length instead of any short word ("autotext" function) in any program.
The launch of a specific playback can be tied to a "hot key". And using this key to launch it at any time you need
The ability to play recorded actions in a cycle any number of times. Set 100,000 cycles and go to sleep, everything will be done by itself.
Ability to insert arbitrary delay into recorded actions. You can delay the start for any period of time, insert a delay command between any actions.

In addition to the advantages, there are some limitations when using the AutoClickExtreme program.

Does not always adequately reproduce recorded actions in games based on DirectX.
There is no way to work with console programs, since working with it is based on other principles for entering information from the keyboard and mouse than Windows applications.

Personal automation is a creative matter, for sure you can come up with some kind of original application of this program.

I will now give you some valuable ideas for using AutoClickExtreme.

In your absence, it is possible to run any programs or processes. Moreover, your computer itself may well do complex things such as launching an Internet connection, connecting to a specific site and performing some actions on it.
It is possible to perform actions for programs that work with large delays. It is better to leave in your absence a "robot" instead of yourself, who will continue the work after the completion of any lengthy process.
Organization of the launch of certain programs and documents when the computer boots up, so that you can immediately start working with them. Another option is to prepare several options for running programs or documents, depending on the type of work. And you won't have to spend time preparing before work.
Customize your own "hot keys" that were not provided in a particular program. Write down the necessary actions with the program, and "hang" them on a specific hot key.
Massively process a large number of documents: databases, images, texts, making some standardized edits.
It is possible to back up valuable documents on your computer. An automated backup of the most important folders to another medium, which would be done without your presence, will protect your work files from loss in case of failures.
If you need to automatically number or calculate something in your work, you can use the standard "calculator" or Excel program, where the data is inserted, the calculation is carried out and the result is then copied to another file.
It is convenient to distribute information from one document to several different ones.

Why does it make sense to automate your work as much as possible with AutoClickExtreme?

You can save time and nerves that you would have spent on routine operations.
Using the call of recorded actions to hotkeys, you can give yourself additional tools for work, saving you even more time.
Eliminate errors completely. The human factor works, and when doing the same type of work, sometimes there will be shortcomings. The computer doesn't make mistakes.

In general, I liked AutoClickExtreme. Interestingly, the demo record draws quite complex images "by hand" in the Paint graphics editor. It's worth looking at.

Summing up, I can say that optimizing and automating your work on the computer is an important topic that allows you to get a lot of benefits. AutoClickExtreme is a very useful tool that I encourage you to try and use.

BIOS update This is a very useful, but at the same time extremely dangerous procedure. Useful because after the release of their products, manufacturers continue to improve it based on the feedback from service centers, their research. Over time, data on errors appear, as well as their corrections. So these are the solutions to hardware-level problems, additional options in the settings appear in new versions of the BIOS management firmware.

The danger of this procedure lies in the complete inoperability after an unsuccessful flashing of the BIOS. In most of these cases, work motherboard or a laptop can be restored only in a service center. And sometimes such a recovery procedure is impossible or is associated with the dismantling of the microcircuit from the motherboard, and its further firmware in a special programmer. And all this costs money.

Attention! Flashing the BIOS is associated with the risk of losing hardware performance. Reflash it only as a last resort, and with sufficient experience for this! If you decide to flash your BIOS for the sake of following the buzzword - give it up!

So, you have decided to flash the BIOS on your laptop. In this article we will try to help you.

Before flashing laptop BIOS

The safest and most reliable way is to flash from DOS with via USB flash drives.
The general principle of flashing the BIOS from under DOS is as follows. You need to copy the file new version BIOS, as well as a special flashing utility (flasher) to a bootable USB device. Reboot laptop, boot from flash drive. Run the flasher using the command line and follow the instructions.

What you need to know before flashing laptop BIOS:

1. Download the latest BIOS only from the official website of the laptop manufacturer. Don't download the beta version. Download the latest tested and working version.

2. The laptop must be turned on through the power supply, and not run on battery power. Best Option will turn on the laptop to the mains through Uninterruptible Power Supply (UPS).

3. The USB flash drive used must be reliable and proven in operation. If you notice any errors related to data loss in the operation of the USB drive, then in no case do not use it.

4. Never power off your laptop during the BIOS update process. Also, never press any keys or buttons on the laptop during this time.

How to flash laptop BIOS

Consider the process of updating the BIOS on the example of a laptop Dell Inspirion 1525.

1. Create a bootable USB flash drive. Read about how to do it quickly and reliably. If you do not have a standard USB flash drive at hand, but your laptop supports booting from the built-in card reader, then use it. To do this, you need to make a bootable memory card from a camera or phone, after saving data from it.

2. Downloading the latest BIOS version from the official website of the laptop. The best way to do this is to use the serial number from the sticker on the bottom of the laptop case. Many manufacturers provide a service on their website to search for the necessary files to download by serial number. Our laptop has Service Tag. By entering it on the manufacturer's website, we find the BIOS file. At the time of this writing, this is version A17 dated December 2, 2009. Moreover, everything we need is already included in one file with the extension *.exe. So, from the official Dell website, download the file 1525_A17.EXE and copy it to our bootable flash drive. Be sure to remember or better write down the name of the downloaded file!

3. Booting from a USB flash drive. To do this, we set the boot from a USB device in the BIOS of the laptop itself. Or we use special keys while turning on the laptop to call up the boot device selection menu. On Dell laptops, this is the function key F12. After loading we will see command line DOS

4. Enter the command to run the BIOS flashing program (file name):
The code:

C:> 1525_A17

5. Launch the DELL programmer shell

The program itself will check the BIOS file for errors and for compliance with its laptop model. If the verification procedure was successful, then press any button on the keyboard to continue.
When you are ready to start the BIOS flashing process, press the " Y"

The laptop BIOS update process will begin
and check the result of the BIOS update
Wait for the moment when the update process is over! Do not turn off the laptop and do not press any keys during this time! After the BIOS flashing is completed and it is successfully checked, the laptop will be overloaded
When the laptop goes into reboot, it may turn off and not turn on for a few seconds. This is fine! Just wait for the laptop to turn on by itself.

6. After flashing the new BIOS version, go into it and set all the settings you need.

Flashing to different models laptops and other manufacturers, of course, may differ. Usually, along with the BIOS files, instructions for flashing it are also supplied. Be sure to read it. In general, all actions are very similar to each other. The main thing is not in a hurry and do everything deliberately!

What to do if the BIOS flashing process fails

If, after updating the BIOS, your laptop stops turning on, or displays an error, do not panic. Save the flash drive with the BIOS file that was used for flashing.

On many modern laptops, there is an emergency recovery system for the original BIOS version. It's just for those cases. Just run this firmware rollback process.

If you do not know what to do in this case, contact the nearest service center. Bring the BIOS file you used. Paid, but they will help you there.

The very fact of flashing is not considered a violation of the manufacturer's warranty. But in case of an unsuccessful result, you may lose the guarantee!
